The following may seem retarded and if so please forgive me.
I use Notesnook to share notes between multiple devices. Any change in notes are updated in real time. What’s good is that text is encrypted. A user is able to change text into different colors and formatting.
I thought to myself, Hey this could be a kind of text messaging app. Notesnook is available on Android and iOS. Maybe this could be a kind of compromise, a sort of alternative to messaging apps?
